@0f1b5961: I apologize if my previous response did not fully answer your question. To provide a more specific answer, the spelling of "hoof" with a "f" instead of "v" is due to the word's origin in Old English. The Old English word for "hoof" was "hōf," which was spelled with an "f." Over time, the spelling of the word evolved, but the "f" spelling remained. So, the spelling of "hoof" with an "f" is a remnant of the word's Old English roots.
